在WinForm中實現列表項的多選功能可以使用ListView控件,并設置其屬性MultiSelect為True,然后通過以下步驟實現多選功能:
listView1.View = View.Details;
listView1.MultiSelect = true;
private void listView1_ItemSelectionChanged(object sender, ListViewItemSelectionChangedEventArgs e)
{
foreach (ListViewItem item in listView1.SelectedItems)
{
// 處理選中項的邏輯
}
}
private void listView1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.ControlKey)
{
listView1.MultiSelect = true;
}
}
private void listView1_KeyUp(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.ControlKey)
{
listView1.MultiSelect = false;
}
}
通過以上步驟,就可以實現在WinForm中實現列表項的多選功能。
